One hundred and thirty-four (134) of 774 tests (17.3%) were clearly positive and were scored 1, 2, or 3; and 11 (1.4%) had questionable results. <jats:italic>Wuchereria bancrofti<\/jats:italic> microfilariae (mf) were detected in 41 of those 133 individuals with an ICT test score \u2265 1 who also had a night blood smear; none of the 11 individuals with questionable ICT results harbored night mf. Cuzick's test showed a significant trend for higher microfilarial densities in groups with higher ICT scores (<jats:italic>P<\/jats:italic> &lt; 0.001). The ICT scores were also significantly correlated with blood mf counts. Because filarial antigen levels provide an indication of adult worm infection intensity, our results suggest that semi-quantitative reading of the ICT may be useful for grading the intensity of filarial infections in individuals and populations.<\/jats:p>","DOI":"10.4269\/ajtmh.13-0245","type":"journal-article","created":{"date-parts":[[2013,9,10]],"date-time":"2013-09-10T02:37:47Z","timestamp":1378780667000},"page":"916-918","source":"Crossref","is-referenced-by-count":33,"title":["Semi-Quantitative Scoring of an Immunochromatographic Test for Circulating Filarial Antigen"],"prefix":"10.4269","volume":"89","author":[{"given":"C\u00e9dric B.","family":"Chesnais","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fran\u00e7ois","family":"Missamou","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S\u00e9bastien D.
